Stage 03 · Capture: Every Inquiry Needs a Next Step

Multi-channel intake is a reliability problem in disguise. Series yield, silent failure modes, and why the leak you can't see is the expensive one.

  • Lead Capture
  • Reliability
  • Growth Engineering

Capture is the least glamorous stage on the map and the one where I find the most money. Not because businesses are careless, but because the failures are silent: nothing errors, nobody complains, and the inquiry simply never existed.

Ariadne's third stage says: "Forms, calls, chat, and inbox inquiries land in one place, get qualified against your criteria, and reach the right person with context." Every clause in that sentence is load-bearing, and each one corresponds to a failure I have found in a real audit.

Series yield, again

An inquiry has to survive a sequence of independent events to become a conversation:

Ycapture  =  yreachysubmitydeliverynoticeyqualifyyassignY_{\text{capture}} \;=\; y_{\text{reach}} \cdot y_{\text{submit}} \cdot y_{\text{deliver}} \cdot y_{\text{notice}} \cdot y_{\text{qualify}} \cdot y_{\text{assign}}

Six terms. Suppose each is 95% — a number most owners would consider excellent for their own business. Then

Ycapture=0.9560.735Y_{\text{capture}} = 0.95^{6} \approx 0.735

Roughly a quarter of inquiries lost, with no stage performing badly and no alarm anywhere. This is the arithmetic behind Sabnis and colleagues' finding that around 70% of marketing-generated leads are never pursued by sales at all Sabnis et al. 2013. That study identified organisational lead-prequalification and rep workload as drivers — structural variables, not effort.

The audit evidence

The InsideSales.com secret-shopper study is the best public accounting of how intake actually fails at scale. They attempted test leads at 14,061 companies. Of those, 4,523 (32%) were eliminated before the test could even run: 309 had no website, 4,031 had no web form, and 183 had a broken form Phillips et al. 2014.

Sit with that. Nearly a third of companies could not receive a routine inbound inquiry. Not "responded slowly" — could not receive it.

Of the 9,538 that did receive one, 4,472 (47%) never responded. Median first phone response was 3 hours 8 minutes; the mean was 61 hours.

The 2011 HBR audit of 2,241 companies found the same shape: 23% never responded Oldroyd et al. 2011.

Silent failure is the design problem

The reason these persist is that they produce no signal. A missing inquiry and a non-existent inquiry look identical from the inside. There is no error, no bounce, no complaint — the prospective customer simply concludes you are not interested and calls someone else.

The engineering answer is to make the absence observable. That means:

One record per inquiry, created at the boundary. Every channel writes to the same store the moment contact happens, before any human judgement. If it is not written, the channel is broken and you will find out.

A heartbeat. A daily count per channel, alarmed on zero. Zero form submissions on a Tuesday is either a slow day or a broken form, and you want to be told which.

A synthetic transaction. Submit a test inquiry through every channel on a schedule and assert it arrives. This is standard practice for production software and essentially unknown in small-business marketing, which is strange, because the cost of an undetected outage is identical.

An acknowledgement that starts a clock. The inquirer gets a specific, time-bounded next step. Recall Batt and Terwiesch's finding that abandonment responds to what the waiting person can observe, not merely to elapsed time Batt & Terwiesch 2015. An acknowledgement is not politeness; it is a queue-state signal that buys you real minutes.

Qualification is part of capture, not sales

The last clause of Ariadne's stage-03 description — "qualified against your criteria" — is where most systems put a human by default. That is a mistake for a specific reason: qualification by memory is high-variance, and by the VUT equation, variance is delay.

Write the criteria down. Not aspirationally — operationally, as a set of field values a machine can evaluate. Sabnis and colleagues found that organisational prequalification is one of the factors that determines whether reps work leads at all. Prequalification is not gatekeeping; it is what makes the handoff cheap enough to actually happen.

The output of stage 03 should be a record a human can act on in thirty seconds without asking anyone a question. If they have to go and find context, you have moved the work rather than done it.
